Fig. 10 is a sectional `view of a stillfurtherI VWatchilug `it is foundthat the distance between the lugsoffdifferent wrist watches varies, andin orderthat theend connection between the watch andthe bracelet maytthe lugs,- it has been customarytomakeend hooks of varying lengths anddetachthemfrom the bracelet and interchanging itwithV a hook of thedesired. dimension for the.` wrist watch. Other methods have been toprovide connecting means to be substituted for `the' Apin whichisfurnished with the wrist watch and extendsbetween thelugs. Such meansmay beY that which projects solid `parts with reduced portions toextendinto' the openings in the lugs. These. openings varyk in size, and thismethod has not been entirely satisfactory; and further, the pins are notof the ornamental character desired. In some instances, attachments havebeen formed where theprojecting parts are'on a buckle or some otherportionwhich is to receive hollow ends ofI asolid portion;` but nowheream IaWare that L there Yhas been an arrangement which will recleive thepinv furnished with the wrist Watch which isof asizei-toaccurately fitbetween the lugs .and to coventhis pin" by forming an ornamental portion4whichwillV extend the entire distance between thelugs of varying sizes;and I have accomplished this by, providing tubular portions withaspringrbetween them all housed in a tubular body; sothat the length ofthe body may be the minimum ,distancebetween lugs to be ac U commodatedandthe tubular body plus the ex` tended-:tubular members may be themaximum distance betweenlthe lugs` to be accommodated; and`theyfollowing is a more detailed description of Vthe present.embodiment of this invention, illustrating-the preferred means bywhichthese adyantageous Aresults may beaccomplished; A

With reference to the drawing, I0 designates thetwristmwatch .havinglugs I I extending out- Wardly .therefrom with a:pin l2extendingfbetween these lugs which may or may not embody a springarrangement for detachment from position. The bracelet to be attached tothe Watch is designated i4, and, is provided with Va connecting devicewhich is commonly called an end hook and which Iv designate generallyl5.

This end hook is illustrated as provi-ded with a tubular body I6 havingslots Il on the under side thereof. Within this body I have providedextension members. I8 which are slidably mounted and ofy a size to fitrather snugly therein andbe guided thereby. Each of these membersconsists essentially of a tube which is provided with a pin i9 to extendinto the slot H in the body and be limited in its movement by the lengthof the slot and the pin abutting the ends thereof.

The extension members I8 are forced outwardly by a spring 20 of ahelical formation and held under compression between the ends 2l of thetubes I8 so that it continually tends to force the tubes I8 outwardlyregardless of the position which they assume relative to the body inwhich they are slidably mounted. `'Ihe spring 2|,is of a helicalformation providing a clear opening through the center thereof whichaligns with the opening 22 in the members I8 and provides a centralopening through all of these parts for the reception of the pin I2 whichextends therethrough and into the lugs II. This pin willbear in thebores 22 in the tubes I8 rather than on the spring, thus allowing thespring freedom of movement to actuate the tubes outwardly.

When the tubes are at their full extent outwardly, as shown in Figures2, 3, and 4, the maximum distance between the lugs II will be providedfor, and the pin I2 extending therebetween will be completely coveredbyfthese ornamental tubes I8. However, when the distance between thelugs is of lesser extent, the tubes may be forced inwardly slightly orforced inwardly sumciently to accommodate the lesser distance betweenthe lugs and where the minimum distance of the lugs is encountered,.thetubes will be completely housed within the body I6 'so thatv they willnot be visible at all and the body I6 will occupy the full space betweenthe lugs. By this arrangementan end hook is provided which will be ofuniversal application to the lugs of awrist watch or to some other likearticle to which it may l be desired to attach it.

I have illustrated in Figures 1 to 8 the body I5 of the end hook asformed integral with the bracelet band I4 by rolling the same from theend of the stock thereof, and when forming the end hook in this manner,I may slot the end of the band in the portion which is toY be rolled androll it about the end tubes with their projecting pins I. and spring 20at the time which :it is formed into the tubular shape of the body IC,thus providing a simple means of assembly.

In Figures '7 and 8 I have reversed the construction of the stoparrangement by providing a pin 25 inthe body I6 of the' end hook and aslot 2l in each of the tubular members, where otherwise the structuresin Figures 7 and 8 are like the structures in the provision in Figures 1tot.Y

In Figure 10 I have illustrated the tubular body It as formed separatefrom the band designated 21 and soldered to it as at' 28, by whicharrangement I may provide a seamless tube, designated 29, if desired,and cut the slots therein for the pin I9.

In Figure 9 I haveillustrated the body I6 as provided with a loop 30 towhich a connecting link 3| is attached to join it to the end link 32 ofthe bracelet, or any other suitable means may be provided for attachingthis connector or end hook when used for connecting a bracelet to thepart to which it is desired it should be detachably connected.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.

I claim:

l. An end hook for a bracelet comprising a tubular body and a pair oftubular members slidable with reference to said body and located thereinto extend the effective length thereof at each end thereof, resilientmeans having a center opening acting on said members to force them out-A wardly, and means for mounting said body and member on the end of abracelet band, said body, member and spring having openings extendingcompletely through the center thereof for the reception of the pin ofWrist watch lugs or the like.

2. An end hook for a bracelet comprising a tubular body and a pair oftubular members slidable with reference to said body and located thereinto extend the effective length thereof at each .l

end thereof, a coiled spring acting on said members to force themoutward1y, cooperating means between said body and members to limit theoutward movement of said members, and means for mounting said body andmember on the end of a bracelet band, said body, member and springhaving an opening extending completely through the center thereof forthe reception of the pin of wrist watch lugs or the like.

3. An end hook comprising an embracing body member, similarly shapedmembers of a size to ilt therein and slidably mounted with referencethereto, and resilient means acting on theA ends of said slidablymounted members to move them outwardly from the body member, said body,

member and spring having an opening extending completely through thecenter thereof for the reception of the pin of wrist watch lugs or thelike.

4. An end hook comprising an embracing body member, similarly shapedmembers of a size to iit therein and slidably mounted with referencethereto, and a coiled spring acting on the ends of said slidably mountedmembers to move them outwardly from the body member, said body, ,i

member and spring having an opening extending completely through thecenter thereof for the reception of the pin of wrist watch lugs or thelike.
